It's designed as a supplementary tool for active malware removal. It lacks the comprehensive protection features of full antivirus suites like Bitdefender, including real-time protection and advanced threat prevention. Use Malwarebytes alongside another antivirus or as a secondary scanner."},{"question":"Which has better detection rates?","answer":"Bitdefender has a slightly higher malware detection rate at 99.7% compared to Malwarebytes' 98.5%, based on AV-TEST and independent lab testing. Both are excellent, but Bitdefender's edge comes from behavioral analysis and machine learning, making it better at detecting zero-day threats."},{"question":"Will either slow down my computer?","answer":"Bitdefender is lighter, consuming only 2-3% CPU during scans with minimal real-time impact. Malwarebytes uses 4-5% CPU during scans. For most users, neither will cause noticeable slowdown, but Bitdefender is the clear winner for system performance."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/bitdefender-vs-malwarebytes","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/bitdefender-vs-malwarebytes), Bitdefender offers comprehensive multi-device protection with stronger malware detection rates (99.7%) and lower system performance impact, while Malwarebytes excels at removing existing infections an","dateModified":"2026-06-15T01:40:13.662Z"},"relatedQuestionsUrl":"https://www.aversusb.net/api/faq/bitdefender-vs-malwarebytes","relatedComparisonsUrl":"https://www.aversusb.net/api/v1/related/bitdefender-vs-malwarebytes","knowledgeGraphUrl":"https://www.aversusb.net/api/knowledge-graph/bitdefender-vs-malwarebytes","claimReviewSchema":{"@context":"https://schema.org","@type":"ClaimReview","@id":"https://www.aversusb.net/compare/bitdefender-vs-malwarebytes#claimreview","url":"https://www.aversusb.net/compare/bitdefender-vs-malwarebytes","inLanguage":"en-US","isAccessibleForFree":true,"conditionsOfAccess":"Free","claimReviewed":"Bitdefender vs Malwarebytes","reviewBody":"Bitdefender offers comprehensive multi-device protection with stronger malware detection rates (99.7%) and lower system performance impact, while Malwarebytes excels at removing existing infections and provides a lighter-weight alternative focused on malware-specific threats rather than full antivirus coverage.","datePublished":"2026-06-15T01:40:13.114Z","dateModified":"2026-06-15T01:40:13.662Z","reviewRating":{"@type":"Rating","ratingValue":5,"worstRating":1,"bestRating":5,"alternateName":"High Confidence"},"author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B","url":"https://www.aversusb.net"},"itemReviewed":{"@type":"WebPage","@id":"https://www.aversusb.net/compare/bitdefender-vs-malwarebytes","url":"https://www.aversusb.net/compare/bitdefender-vs-malwarebytes","name":"Bitdefender vs Malwarebytes","inLanguage":"en-US"}}}
